Share X LinkedIn

"Dunning" is derived from the 17th-century word "dun," meaning to demand payment for a debt. In SaaS, it refers to the automated process of communicating with customers about failed payments.

# The Dunning Lifecycle

  1. Pre-Dunning: Reminding customers before their card expires.
  2. Active Dunning: The series of messages sent after a failure.
  3. Cancellation: The final step when all recovery attempts fail.

# Automation vs. Personalization
